摘要
以氯化锌为原料,柠檬酸为模板剂制备了锌基复合气凝胶,通过场发射扫描电镜（FESEM）、高分辨透射电镜（HRTEM）、X射线衍射（XRD）、N2吸/脱附以及红外谱图（FTIR）对气凝胶的结构进行了表征,结果表明：锌基复合气凝胶是由大量纳米级的球状颗粒堆积而成,具有典型的三维网络结构,其骨架是由大量非晶态的颗粒组成的;气凝胶具有较高的比表面积为177 m2/g,其孔径分布主要集中在10~60 nm,为介孔材料。
In this study, we developed the Zinc-based composite aerogel through dispersed inorganic sol-gel method using eitrie acid as template, which employed the properties of high apparent specific surface areas. The monolithic Zinc-based composite aerogel is successfully prepared on the basis of the dispersed inorganic sol-gel method with ZnC12 and citric acid via supercritical fluid drying. By adopting FESEM,HRTEM,XRD, FTIR and BET,we research that the aerogel has a typical three-dimensional porous structure. The morphology of aerogel was evaluated by field-emmision scanning eleetron microscope （FESEM） and high-resolution transmission electron microscope （HRTEM）,which suggest that the aerogel was made up of 3-D networks. The N2 adsorption/desorption shows that the aerogel has high BET surface area of 177 m2/g,average pore diameter about 10 -60 nm,which means the aerogel possesses the typical characteristic of mesopore.
